BUTTON-FASTENER.

Specification of Letters Patent.

Patented Apr. 4,1916.

Application filed January 17, 1914. Serial No. 812,820.

T 0 all whom it may concern:

Be it known that I, JOHN M. DAHLGREN, a citizen of the United States,residing at Bethune, in the county of Kershaw and State of SouthCarolina, have invented new and useful Improvements in Button-Fastenersof which the following is a specification. This invention relates tostapling tools, and particularly to that class of tools designed forsecuring shoe fasteners to the uppers of shoes.

7 An object of the invention is the provision of a tool of thischaracter which will be designed for; use in applying fasteners of aparticular type and embodying a plurality of securing spurs that areadapted to be extended through the material of the uppers and to besubsequently clenched against the material at the back thereof onmanipulating the implement.

Another object of the invention is the provision of a tool ofth scharacter wherein one of the clamping plates'or portions thereof will bedesigned to initially accommodate the spurs on the operation of securingthe fastener upon the shoe and before upsetting the spurs.

With these and other objects in view, the invention cons'sts of certainnovel features of construction, combination and arrangement of parts, aswill be hereinafter described and claimed.

In the accompanying drawings :-F igure 1 is a perspective view of thedevice; Fig 2 is a plan view of one member thereof; Fig. 3 is a planview of another member thereof; Fig. 4 is a section through a portion ofa shoe. showing the manner of initially connecting the fastener thereto;Fig. 5 is a perspective view of the fastener; and Fig. 6 is a s'milarview, showing another form of fastener.

The tool herein shown is described as essentially important to a properapplication to a shoe of such form of fastener as shown at A in Fig. 4and in Fig. 5 in detail. The fastener is formed from a single blank ofmaterial having a rectangular body 2 provided at its corners withsubstantially V-spurs C which extend at right angles to the direction ofthe body of the plate and which are adaptedto be extended through thematerial of the shoe as shown in Fig. 4: and to be subsequently upsetagainst the back of the material in a manner to be hereinafter fullyexplained.

At the center the body of the fastener is provided with a singleaperture D and extending therethrough is a loop E, which is adapted tobe connected in the eye F of an ordinary button G., In order toaccommodate the parts of the fastener herein specifically referred to toeffect a secure application of the fastener to the material of the shoeI construct the stapling device of companion members 1 and 2, the formerhaving a substantially rectangular plate 3 of a configuration conformingsomewhat to that of the body of the fastener and of a size slightlyexceeding the same. From one side of the plate 3 of the member 1 isextended a shank The other member 2' of the stapling de-* Vice isprovided with'a plate 8 of a size preferably co-extensive with that ofthe plate 3 of the member 1 and adjacent to the corners and within theboundary of the body of the fastener said plate 8 is provided withrectangular slots 9. From one side of the plate is extended the shank 10which terminates in a handle 11 similar to the handle 5. The width ofthe handle 11 is such that it may be extended through the slot 6, whilethe width of the shank 10 is of a size whereby it may be occupied in thebranch 7 of said slot 6 after the member 2 is twisted at right angles tothat position which it initially occupies when extending the handle 11through the slot 6. In this manner the branch 7 serves to receive theshank 10 of the member 2, whereby the two members are free for pivotalmovements relatively and the plates 3 and 8 of both members are c0actively associated whereby they may be advanced with proper pressureagainst the opposite sides of the body of the fastener and cause thelatter to be securelyconnected with the material, as will be understood.The plate 3 of the member 1 of the device is provided with a slot 12having its'closed end 13 disposed near the center of the plate.

In describing the use of the device, it is said that the fastener A isinitially placed against that portion of the shoe to which the fasteneris to be permanently connected. The spurs C are then driven through thematerial of the shoe as shown in Fig. 4. After thus arranging thefastener upon the shoe, the stapling device is controlled by the handand the plates 8 and 8 are made to lie respectively at the oppositesides of the material of the shoe. The loop E is extended into the slot12 until it engages the closed end 13 of said slot. The spurs C of thebody of the fastener are then properly positioned relatively of theslots 9 of the plate 8 and both plates are then advanced toward eachother by applying pressure to the handles 5 and 11. The plate is thensecured to the material of the shoe in a manner that will warrant afinal upsetting of the terminals of the spurs G against the back of theshoe. The staple, with a button thereon, is placed immediately under theplate 3 with the button and member E extending through the slot 12, theshoe upper or part to which the button is to be fastened then beingplaced upon the member 8 and the handles 5 and 11 brought together,whereupon the staple points will be forced through the leather andthrough the holes 9. The tool then being opened and the upper slidforward slightly, the jaws can be again closed and the staples will beclenched. 7

Another form of fastener which may be fastened to a shoe by means of myimproved tool is shown in Fig. 6 and comprises a base having integralspurs C and also having, projecting from the opposite side, at thecenter, a shank H and a button head I.

I claim The herein described stapling vtool com prising a pair ofmembers each having a plate forming a j aw and a handle shank extendingfrom one side of the plate, the plate of one member being provided withopenings near its corners, the plate of the other member being providedwith a slot which extends from near its center to its outer side, theshank of the last named-member having an offset portion and beingprovided with a T-shaped slot, the head of which is located transverselyin said offset p0rtion,'the shank of. the first named memberextendingthrough the head of said slot and co-acting therewith and withsaid olfset portion of the first named member to detachably'pivotallyconnect said members together and with their shanks in crossed relation,the length of the branch of the T-shaped' slot being such as to enablethe shank of the firstnamed member to be initially inserted- Copies ofthis patent may be obtained for five cents each, by addressing thevCommissioner of latents 7 Washington, D. C.
